The Harrisonburg Republican has scheduled a news conference for Wednesday in Richmond. Unofficial state election results show Democratic Sen. Mark Herring with a narrow lead over Obenshain.

After provisional ballots were tallied late Tuesday in Fairfax County, Herring declared himself the winner. Obenshain did not concede, saying he would wait for the state's certification of the Virginia-wide vote. That occurs Nov. 25.

Obenshain did not say whether he would seek a recount.

The State Board of Elections shows Herring with a 106-vote lead. That number does not include the Fairfax County votes added to both men's column Tuesday night.
